Abstract:
A compact quad-band rectangular wide-slot antenna is developed for GPS L1 band, 2.5/3.5/5.5 GHz WiMAX and 2.4/5.2/5.8 GHz WLAN applications. The planar antenna consists of an L-shaped microstrip feed line and three stubs extending from the wide-slot on the ground plane. The performance of the antenna is enhanced by etching meander line on the top of the wide-slot. The proposed antenna has a size of 36*42*1 mm3 which is more compact than the previously reported antennas for the same application. The antenna has been simulated, fabricated and measured successfully. The measured results show that the antenna has the impedance bandwidths of 160 MHz (1.54-1.7 GHz), 380 MHz (2.38-2.76 GHz), 570 MHz (3.2-3.77 GHz) and 1130 MHz (5.12-6.25 GHz) for S11 ≤ -10 dB. In addition, good radiation characteristics and stable antenna gains over the operating bands are obtained.
